Abstract
The utility model belongs to the field of gearboxes, and particularly discloses a lubricating system pressure releasing device of a power gear shifting gearbox. The lubricating system pressure releasing device comprises an oil cylinder body, an end cover, a lubricating piston and a spring. The oil cylinder body is sealed through the end cover. A small pressure releasing hole II and a small pressure releasing hole I are formed in the oil cylinder body from the closed end to the open end in sequence. The lubricating piston is located in the small pressure releasing hole I, the spring is located in the closed end of the oil cylinder body, the end cover is provided with a lubricating oil channel, and an oil groove is formed in the lubricating piston. When the lubricating oil pressure is normal, the small pressure releasing hole I is blocked through the lubricating piston. When the lubricating oil pressure is high, the lubricating piston compresses the spring under the action of the lubricating oil pressure, the small pressure releasing hole I is exposed, redundant lubricating oil is discharged out of the small pressure releasing hole I, and the air in the oil cylinder body is exhausted out of the small pressure releasing hole II. The lubricating system pressure releasing device is obvious in pressure releasing effect, stable oil pressure can be obtained, the service life of parts can be prolonged, abrasion of friction sheets is reduced, transmission efficiency is high, and the lubricating system pressure releasing device is simple in structure, convenient to machine and assemble and low in cost.
Description
Technical field
The utility model relates to gearbox field, specifically, relates to a kind of dynamic power shift gear box lubrication system pressure relief device.
Background technique
Gearbox inner components will obtain longer operating life, continual and steady lubricated be crucial.Continual and steady lubricated needs keeps the stable of gearbox internal lubrication oil pressure, and oil pressure is too low, easily causes component lack of lubrication, shortens the working life of component; Oil pressure is too high, and clutch friction plate is in the position of half combination, affects variable speed operation, can aggravate the wearing and tearing of friction plate simultaneously, reduces transmission efficiency.
Model utility content
For addressing the above problem, the utility model provides a kind of dynamic power shift gear box lubrication system pressure relief device simple in structure.
Dynamic power shift gear box lubrication system pressure relief device described in the utility model, comprises cylinder body and end cap, and cylinder body seals by end cap, also comprises lube pistons and spring; On cylinder body, from closed end to opening end, set gradually pressure release aperture II and pressure release aperture I, lube pistons is positioned at pressure release aperture I place, and spring is positioned at cylinder body closed end, and end cap is provided with grease channel.
Improve as one, gear box is provided with lubricated valve opening, in lubricated valve opening, be provided with lube pistons and spring, on lubricated valve opening, from closed end to opening end, set gradually pressure release aperture II and pressure release aperture I, lube pistons is positioned at pressure release aperture I place, spring is positioned at the closed end of lubricated valve opening, and lubricated valve opening seals by end cap, and end cap is provided with grease channel.
Working principle of the present utility model is: when lubrication pressure is normal, the lubricated piston of pressure release aperture I is blocked; In the time that lubrication pressure is high, lubricant oil enters in cylinder body or lubricated valve opening by the grease channel on end cap, lube pistons is at the effect lower compression spring of lubrication pressure, then pressure release aperture I is exposed, unnecessary lubricant oil releases from pressure release aperture I, then spring return function, lube pistons is blocked pressure release aperture I again, and it is normal that oil pressure recovers.The effect of pressure release aperture II is by the Bas Discharged remaining in cylinder body, prevents lube pistons compressed air to do work, cannot pressure release.
Preferably, lube pistons is provided with lubricating channels, and described lubricating channels is the ring structure around lube pistons, and annular ditch groove can make lube pistons surface form equal force feed film, prevents lube pistons pressurized inequality clamping stagnation in cylinder body hole slot.
Compared with prior art, the beneficial effects of the utility model are: pressure release effect is remarkable, in gearbox, can obtain more stable oil pressure, and then increase the working life of component; Can reduce the wearing and tearing of friction plate, improve transmission efficiency; Simple in structure, processing, easy to assembly, cost is low; Can this pressure relief system be set on cylinder body in conjunction with the structure of gearbox, also can on gear box, arrange separately.
